To all whom it mayoncem.'

Be itknown that I, WILLIAM WESTMAN, a citizen of the United States,residing at Essex, in the county of Page and St-ate of Iowa, haveinvented certain new and useful Improvements in Trucks, of which thefollowingis a specification, reference being had p to the accompanyingdrawings.

This invention comprehends certain new and useful improvements intrucks, and relates particularly to a truck designed for use in movingstoves. 4 p v i The invention has for its primary object a .simpledurable and efficient construction of devicenof this character by theuse of which a stove maybeeasily elevated and detached from its base andeasily rolled from one place to another, as desired, the inventionconsisting in certain constructions and arrangements of the parts that Ishall hereinafter` describe and claim.

For a full understanding of the invention reference is to be hadto thefollowing description and accompanying drawing in whichz-f l 1 f Figureluis plan view of a stove truck constructed .in 'accordance with myinvens tion. Figf. isV aside elevation thereof. Fig. 3is an enlargedsectional view on the line 3 3 of. Fig.-1, and, Fig-4 is a trans# versesectional view-'on theV line 4 4 of Fig. 2.

Corresponding and like parts are referred to in the followingdescription and designated in the accompanying drawing by like referencecharacters-f v u My improved stove truck includes a preferablyrectangular frame embodying side bars 1 and end'bars 2 joined togetherat the corners of the frame by rivets or similar fasteningde'vices',lplate braces 3 being located at the corners of the frame in order toinsure therigid'ity thereof. The frame also includes Vdiagonal arms 4which extend in-v wardly from the corner braces 3 and whichmay beintegral parts thereof, they inner ends' of thearms being joined to aframe` riig l5.

The diagonally disposed arms 4; ofthe frame of my device support'insuitable bearings shafts 6 which extendmlongitudina'lly ofthe diagonalarms, as shown, and which are provided at their inner ends with bevelpini'ons 7, all of said pinions meshing with a miter gear wheel 8 theteeth of which face downwardly and which is secured to a central shaft9' held by a Cotter pin orthe like,

as clearly illustrated in the drawings, The shafts G are provided attheir outer ends with bevel pinions 10, said lastnamed pinions meshingrespectively with horizontally disposed bevel pinions 1 1 which areinteriorly threaded as indicated; at 12 for engagement with ,theexterior threads of screw jacks 13 which pass through the threadedopenings of the pinions 11 and are suspended thereby. 'l

In order to operate the miter gear 8, a pinion 111 is disposed inmeshing relation thereto, said pinion being secured to the inner'end ofan actuating shaft 15 which is supported on a frame arm 4 and which isprovided at its outer end with a squared tory to being rolled underneaththe body .portion of a stove according to the height of the stove to bemoved, whereby it will'not be necessary, under some circumstances, to

rotate the shaft 1'5 for any length of time in .y

order to yeffect. the engagement of the revoluble heads of the jackscrews 13 with the bottom of the stove.

To render the truck.

itself capable, of being elevated within cere,` 4

tain limits, for this purpose, I mount theground or traveling wheels 17in brackets 18 which are pivotally connected to the sides of the truckframe by apertured ear-s 19 and pivot -bolts 2O passing therethrough.

The brackets extend underneath the sides, of

the frames at the front and rear ends there;

one edge of each bracket constituting a shoulder designated 21 adaptedto bear v against the underside of the truck frame to supportl thelat-ter inl its relatively low v sdckets being arranged inlongitudinally ex- `handing series. In the present instance, there arethree sockets in each set, but it is to be understood that the inventionis not limited to this or any number of sockets. It 'willi thus beseenthat the frame may be raised and the wheel brackets 18 swung inwardlytoward each other and secured in diterent adjusted positions tovation'fof the truck frame.

y Preferably, each bracket, 18" is formed,

adjoining its pivot .ears 19 with inwardly turned lugs 27 which togetherconstitute a shoulder adapted to abntagainst the under side of the truckframe when the brackets 18 have been swung inwardly to relativelyvertical positions so las to hold the truck'rame atts highestelevation.. Y

From'the foregoing description in connection with the accompanyingdrawing the i v,operation of my improved' stove truck will be apparent.In-the practical use vof the device the frame is elevated as required soas to reduce the gack raising operation to av minimum and the truck 'isthen rolled underneath the body of the stove, the, base unscrewedr fromthe body and the shaft 15 rotated so as to raise the 'jackscrews 13 andthev stove body, supported thereby. The base can then b'e taken away,for the: ltruck and thel rolled to any other desired point.

veo

'l Any suitable handles such as those indicated at 27 are secured to theframe of the truck whereby vthe latter may be easily,

rolled over the floor.

The jack screws 13 are each formed with longitudinal groovesl?)adesigned to receive tongues or splines A32* formed onthe plates 3 orarms 4, whereby the jacks will bev raised when the pinion's 11 areturned.

' It is to be understood 'that while I have shown the braces 23 asarranged in pairs, the innermost braces maybe omitted, if desir-ed. Tosecure the ears 19 in. place, their pivot bolts 20 pass through blocks2OEl that are' riveted or otherwise secured-to the angle iron side barsof the frame-work.

vll' le the accompanying drawing dis- `ntoi' my invention, it is to beunderi that the invention 1s not limited there- .ut that various changesmay be'made leaving a cleartrack stove body may be' what I believe to bethe preferred veinin the construction, arrangement and proportionsof'the parts without departing from the'scope of the invention, asdelined in the appended claims.

What I claim is 1. A truck'of the character described, embodying a wheelsupported frame-work, a miter gear wheel mounted in said framework andsupported thereby, a plurality of bevel pinions meshing -withsaidgearwheel, shafts, to the inner ends of which said pinions are connected,'the' shafts extending radiallyv and outwardly from the gear wheel, theframe-work embodying diagonal arms on which the shafts are journaled,bevel pinions secured to the the respective shafts, with the last namedpinions, and formed with' threaded openings a d jack screws mounted inthe corners of lthe 'frame-work and having threaded engagement with theopenings of the last named pinions, and means for turning said mitergear wheel, whereby to simultaneously rotate the shafts and elevate thescrews. f

2. A truck of the 'character described, including a framework embodyinside bars, wheel brackets'l provi ed lwith apertured ears embracing thesides of the frame-work and. pivotally connected thereto, wheelsjournaled in the respective vbrackets, the rear sides of the bracketsbeing adapted to abut against ,the bottom of the frame-work to` hold theframe-work ina relatively low position, the brackets being formed inadvance .of their pivots with in' wardly turned lugs constitutingshoulders adapted toengage the under lside of they frame-work with thebrackets Vmoved inwardly and the frame-work vsupported. in 4a,relatively high position, and braces pivotally connected to thetrunnions of the wheels and provided at their upper and inner ends withclamping screws 'working in the slots of the frame-work side bars. 'v

3. A truck of the character described, including a wheel supportedframe-work, embodying side and end bars, corner plates connected to saidside. and end bars, diagonally extending arms formedintegral with the,corner yplates and extending inwardly therefrom, a frame ring `securedto the inner ends of said arms,l a miter gear wheel '80 o uter ends ofbevel pinlons'meshlng slotted supported on said frame ring and formedwith. downwardly facing teeth, pinions meshing with said gear wheel,

shafts jour- ,naled' o n the diagonal arms and carrying 'said pinions,-jack screws working in the corner plates, bevel pinions secured to theouter ends of said shafts, horizontallyv disposed bevelpinions, meshingwith the last namedl pinions and formed with threaded .openingsextendingtherethrough, the jack screws working-through said openings and heldfrom rotating therein, the frame also iso including another arm, a shaftmounted on my signature in the presence of two Withis' 'mmed arm and agevel pinion4 carried messes. y sai last ynamed sha t uid meshnr with f1 y T the mter gearA Wheel, whereby the trnng VILLIAM WESTMN 5 of .saidshaft will rotatejall of. the other VVnesses:`
